This chapter presents the commands to configure and maintain Cisco IOS voice, video, and fax applications. The commands are presented in alphabetical order beginning with Si. Some commands required for configuring voice, video, and fax may be found in other Cisco IOS command references. Use the command reference master index or search online to find these commands.
For detailed information on how to configure these applications and features, refer to the Cisco IOS Voice, Video, and Fax Configuration Guide.
signal
To specify the type of signaling for a voice port, use the signal command in voice-port configuration mode. To restore the default value for this command, use the no form of this command.
FXO and FXS Voice Ports
signal {loop-start | ground-start}
no signal {loop-start | ground-start}
E&M Voice Ports
signal {wink-start | immediate | delay-dial}
no signal {wink-start | immediate | delay-dial}
Syntax Description
Defaults
Loop-start for FXO and FXS interfaces; wink-start for E&M interfaces.
Command Modes
Voice-port configuration
Command History
Usage Guidelines
This command applies to analog voice ports only.
Configuring the signal command for an FXO or FXS voice port changes the signal value for both voice ports on a voice port module (VPM) card.
Note
If you change the signal type for an FXO voice port on Cisco 3600 series routers, you need to move the appropriate jumper in the voice interface card of the voice network module. For more information about the physical characteristics of the voice network module, refer to the installation documentation, Voice Network Module and Voice Interface Card Configuration Note, that came with your voice network module.
Configuring this command for an E&M voice port changes only the signal value for the selected voice port. In either case, the voice port must be shut down and then activated before the configured values will take effect.
Some PBXs will miss initial digits if the E&M voice port is configured for Immediate signaling. If this occurs, use Delay-Dial signaling instead. Some non-Cisco devices have a limited number of DTMF receivers. This type of equipment must delay the calling side until a DTMF receiver is available.
Examples
The following example configures ground start signaling on the Cisco 3600 series as the signaling type for a voice port, which means that both sides of a connection can place a call and hang up:
voice-port 1/1/1signal ground-startsignal keepalive
To configure the keepalive signaling packet interval for Cisco trunks and FRF.11 trunks, use the signal keepalive command in voice-class configuration mode. To restore the default value, use the no form of this command.
signal keepalive number
no signal keepalive number
Syntax Description
number
Specifies the keepalive signaling packet interval, in seconds. The valid range is from 1 to 65,535.
Defaults
A keepalive packet is sent every 5 seconds.
Command Modes
Voice-class configuration
Command History
Usage Guidelines
Before configuring the keepalive signaling interval, you must use the voice class permanent command in global configuration mode to create a voice class for the Cisco trunk or FRF.11 trunk. The voice class must then be assigned to a dial peer.
Examples
The following example, beginning in global configuration mode, sets the keepalive signaling interval to 3 seconds for voice class 10.
voice class permanent 10signal keepalive 3exitdial-peer voice 100 vofrvoice-class permanent 10Related Commands
signal pattern
To define the ABCD bit patterns that identify the idle and out-of-service (OOS) states for Cisco trunks and FRF.11 trunks, use the signal pattern command in voice-class configuration mode. To remove the signal pattern setting from the voice class, use the no form of this command.
signal pattern {idle receive | idle transmit | oos receive | oos transmit} bit-pattern
no signal pattern {idle receive | idle transmit | oos receive | oos transmit} bit-pattern
Syntax Description
Defaults
Command Modes
Voice-class configuration
Command History
Usage Guidelines
Before configuring the signaling pattern, you must use the voice-class permanent command in global configuration mode to create a voice class for the Cisco trunk or FRF.11 trunk. After you define the voice class, you assign it to a dial peer.
Idle Patterns
An idle state is generated if the router detects an idle signaling pattern coming from either direction. If an idle pattern is configured for only one direction (transmit or receive), an idle state can be detected only in the configured direction. Therefore, you should normally enter both the idle receive and the idle transmit keywords.
To suppress voice packets whenever the transmit or receive trunk is in the idle state, use the idle receive and idle transmit keywords in conjunction with the signal timing idle suppress-voice command.
OOS Patterns
An OOS state is generated differently in each direction under the following conditions:
•
•
To suppress voice packets whenever the transmit or receive trunk is in the OOS state, use the oos receive and oos transmit keywords in conjunction with the signal timing oos suppress-voice command.
To suppress voice and signaling packets whenever the transmit or receive trunk is in the OOS state, use the oos receive and oos transmit keywords in conjunction with the signal timing oos suppress-all command.
PBX Busyout
To "busy out" a PBX if the network connection fails, set the oos receive pattern to match the seized state (busy), and set the signal timing oos timeout value. When the timeout value expires and no signaling packets have been received, the router will send the oos receive pattern to the PBX.
Use the busy seized pattern only if the PBX does not have a specified pattern for indicating an OOS state. If the PBX has a specific OOS pattern, use that pattern instead.
Examples
The following example, beginning in global configuration mode, configures the signaling bit pattern for the idle receive and transmit states:
voice class permanent 10 signal keepalive 3 signal pattern idle receive 0101 signal pattern idle transmit 0101 exitdial-peer voice 100 vofrvoice-class permanent 10The following example, beginning in global configuration mode, configures the signaling bit pattern for the out-of-service receive and transmit states:
voice class permanent 10 signal keepalive 3 signal pattern oos receive 0001 signal pattern oos transmit 0001exitdial-peer voice 100 vofrvoice-class permanent 10The following example restores default signaling bit patterns for the receive and transmit idle states:

voice class permanent 10 signal keepalive 3 signal pattern oos receive 0001 signal pattern oos transmit 0001exitdial-peer voice 100 vofrvoice-class permanent 10Related Commands
signal sequence oos
To specify which signaling pattern is sent to the PBX when the far-end keepalive message is lost or an alarm indication signal (AIS) is received from the far end, use the signal sequence oos command in the voice-class configuration mode. To restore the default value, use the no form of this command.
signal sequence oos {no-action | idle-only | oos-only | both}
no signal sequence oos
Syntax Description
Defaults
Both idle and OOS signaling patterns are sent.
Command Modes
Voice-class configuration
Command History
Usage Guidelines
Before configuring the idle or OOS signaling patterns to be sent, you must use the voice class permanent command in global configuration mode to create a voice class for the Cisco trunk or FRF.11 trunk. After you finish defining the voice class, you assign it to a dial peer.
Use the signal sequence oos command to specify which signaling pattern) to send. Use the signal pattern idle receive or the signal pattern oos receive command to define the bit patterns of the signaling patterns if other than the defaults.
Examples
The following example, beginning in global configuration mode, defines voice class 10, sets the signal sequence oos command to send only the idle signalin pattern to the PBX, and applies the voice class configuration to VoFR dial peer 100.

signal timing idle suppress-voice
To configure the signal timing parameter for the idle state of the call, use the signal timing idle suppress-voice command in voice-class configuration mode. To restore the default value, use the no form of this command.
signal timing idle suppress-voice seconds
no signal timing idle suppress-voice seconds
Syntax Description
seconds
Duration of the idle state, in seconds, before the voice traffic is stopped. The valid range is from 0 to 65,535.
Defaults
No signal timing idle suppress-voice timer is configured.
Command Modes
Voice-class configuration
Command History
Usage Guidelines
Before configuring the signal timing idle suppress-voice timer, you must use the voice class permanent command in global configuration mode to create a voice class for the Cisco trunk or FRF.11 trunk. The voice class must then be assigned to a dial peer.
The signal timing idle suppress-voice command is used when the signal-type command is set to transparent in the dial peer for the Cisco trunk or FRF.11 trunk connection. The router stops sending voice packets when the timer expires. Signaling packets are still sent.
To detect an idle trunk state, the router or concentrator monitors both transmit and receive signaling for the idle transmit and idle receive signaling patterns. These can be configured by the signal pattern idle transmit or signal pattern idle receive command, or they can be the defaults. The default idle receive pattern is the idle pattern of the local voice port. The default idle transmit pattern is the idle pattern of the far-end voice port.
Examples
The following example, beginning in global configuration mode, sets the signal timing idle suppress-voice timer to 5 seconds for the idle state on voice class 10.

signal timing oos
To configure the signal timing parameter for the out-of-service (OOS) state of the call, use the signal timing oos command in voice-class configuration mode. To restore the default value, use the no form of this command.
signal timing oos {restart | slave-standby | suppress-all | suppress-voice | timeout} seconds
no signal timing oos {restart | slave-standby | suppress-all | suppress-voice | timeout} seconds
Syntax Description
Defaults
No signal timing OOS pattern parameters are configured.
Command Modes
Voice-class configuration
Command History
Usage Guidelines
Before configuring signal timing OOS parameters, you must use the voice class permanent command in global configuration mode to create a voice class for the Cisco trunk or FRF.11 trunk. The voice class must then be assigned to a dial peer.
You can enter several values for this command. However, the suppress-all and suppress-voice options are mutually exclusive.
Examples
The following example, beginning in global configuration mode, configures the signal timeout parameter for the OOS state on voice class 10. The signal timing oos timeout command is set to 60 seconds.

Defaults
No restart attempt is made if the trunk becomes OOS.
Command Modes
Voice-class configuration
Command History
Usage Guidelines
Before configuring signal timing OOS parameters, you must use the voice class permanent command in global configuration mode to create a voice class for the Cisco trunk or FRF.11 trunk. You then assign the voice class to a dial peer.
The signal timing oos restart command is valid only if the signal timing oos timeout command is enabled, which controls the start time for the OOS state. The timer for the signal timing oos restart command does not start until the trunk is OOS.
Examples
The following example, beginning in global configuration mode, creates voice class 10, sets the OOS timeout time to 60 seconds and sets the restart time to 30 seconds:

signal timing oos suppress-all
To configure the router or concentrator to stop sending voice and signaling packets to the network if it detects a transmit out-of-service (OOS) signaling pattern from the PBX for a specified time, use the signal timing oos suppress-all command in voice-class configuration mode. To restore the default value, use the no form of this command.
signal timing oos suppress-all seconds
no signal timing oos suppress-all
Syntax Description
seconds
Delay duration, in seconds, before packet transmission is stopped. There is no default duration. The range is from 0 to 65,535.

Command Modes
Dial-peer configuration
Command History
Usage Guidelines
This command applies to Voice over Frame Relay (VoFR) and Voice over ATM (VoATM) dial peers. It is used with permanent connections only (Cisco trunks and FRF.11 trunks), not with switched calls.
This command is used to inform the local telephony interface of the type of signaling it should expect to receive from the far-end dial peer. To turn signaling off at this dial peer, select the ext-signal option. If signaling is turned off and there are no external signaling channels, a "hot" line exists, enabling this dial peer to connect to anything at the far end.
When you connect an FXS to another FXS, or if you have anything other than an FXS/FXO or E&M/E&M pair, the appropriate signaling type on Cisco 2600 series and 3600 series routers is ext-signal (disabled).
If you have a digital E1 connection at the remote end that is running cept/MELCAS signaling and you then trunk that across to an analog port, you should make sure that you configure both ends for the cept signal type.
If you have a T1 or E1 connection at both ends and the T1/E1 is running a signaling protocol that is neither EIA-464, or cept/MELCAS, you might want to configure the signal type for the transparent option in order to pass through the signaling.
Examples
The following example shows how to disable signaling on a Cisco 2600 or 3600 series router or on a Cisco MC3810 multiservice concentrator for VoFR dial peer 200, starting from global configuration mode:

12.1(1)T
This command was integrated into Cisco IOS Release 12.1(1)T.
Usage Guidelines
You can configure a maximum of two sessions, one for each signaling link. In a redundant Media Gateway Controller configuration, session-0 is configured to one MGC and session-1 is configured to the other.
The Media Gateway Controller must be configured to send messages to the local port, and it must be configured to listen on the remote port.
You must reload the router whenever you remove a session or change the parameters of a session.
Examples
The following example sets up two sessions on a Cisco 2611:
ss7 session-0 address 255.251.255.255 7000 255.255.255.254 7000ss7 session-1 address 255.255.255.252 7002 255.255.255.254 7001

12.1(1)T
This command was integrated into Cisco IOS Release 12.1(1)T.
Usage Guidelines
The cumulative acknowledgment timer determines when the receiver sends an acknowledgment. If the timer is not already running, it is initialized when a valid data, null, or reset segment is received. When the cumulative acknowledgment timer expires, the last in-sequence segment is acknowledged. The RUDP typically tries to "piggyback" acknowledgments on data segments being sent. However, if no data segment is sent in this period of time, it sends a standalone acknowledgment.
Examples
The following example sets up two sessions and sets the cumulative acknowledgment timer to 320 milliseconds for each one:
ss7 session-0 address 255.255.255.251 7000 255.255.255.254 7000ss7 session-0 cumack_t 320ss7 session-1 address 255.255.255.253 7002 255.255.255.254 7001ss7 session-1 cumack_t 320Related Commands

12.1(1)T
This command was integrated into Cisco IOS Release 12.1(1)T.
Usage Guidelines
The null segment timer determines when a null segment (keepalive) is sent by the client Cisco 2600 series router. On the client, the timer starts when the connection is established and is reset each time a data segment is sent. If the null segment timer expires, the client sends a keepalive to the server to verify that the connection is still functional. On the server, the timer restarts each time a data or null segment is received from the client.
The value of the server's null segment timer is twice the value configured for the client. If no segments are received by the server in this period of time, the connection is no longer valid.
To disable keepalive, set this parameter to 0.
Examples
The following example sets up two sessions and sets a keepalive of 1,800 milliseconds for each one:
ss7 session-0 address 255.255.255.251 7000 255.255.255.254 7000ss7 session-0 kp_t 1800ss7 session-1 address 255.255.255.253 7002 255.255.255.254 7001ss7 session-1 kp_t 1800Related Commands

12.1(1)T
This command was integrated into Cisco IOS Release 12.1(1)T.
Usage Guidelines
The cumulative acknowledgment counter records the number of unacknowledged, in-sequence data, null, or reset segments received without a data, null, or reset segment being sent to the transmitter. If this counter reaches the configured maximum, the receiver sends a standalone acknowledgment (a standalone acknowledgment is a segment that contains only acknowledgment information). The standalone acknowledgment contains the sequence number of the last data, null, or reset segment received.
If you set this parameter to 0, an acknowledgment is sent immediately after a data, null, or reset segment is received.
Examples
The following example sets up two sessions and in each session sets a maximum of two segments for receipt before acknowledgment:
ss7 session-0 address 255.255.255.251 7000 255.255.255.254 7001ss7 session-0 m_cumack 2ss7 session-1 address 255.255.255.253 7002 255.255.255.254 7000ss7 session-1 m_cumack 2Related Commands

This command was integrated into Cisco IOS Release 12.1(1)T.
Usage Guidelines
The out-of-sequence acknowledgment counter records the number of data segments that have arrived out of sequence. If this counter reaches the configured maximum, the receiver sends an extended acknowledgment segment that contains the sequence numbers of the out-of-sequence data, null, and reset segments received. When the transmitter receives the extended acknowledgment segment, it retransmits the missing data segments.
If you set this parameter to 0, an acknowledgment is sent immediately after an out-of-sequence segment is received.
Examples
The following example sets up two sessions and sets a maximum number of four out-of-sequence segments for each session:
ss7 session-0 address 255.255.255.251 7000 255.255.255.254 7001ss7 session-0 m_outseq 4ss7 session-1 address 255.255.255.253 7002 255.255.255.254 7000ss7 session-1 m_outseq 4Related Commands

12.1(1)T
This command was integrated into Cisco IOS Release 12.1(1)T.
Usage Guidelines
The retransmission timer is used to determine whether a packet must be retransmitted and is initialized each time a data, null, or reset segment is sent. If an acknowledgment for the segment is not received by the time the retransmission timer expires, all segments that have been transmitted—but not acknowledged—are retransmitted.
This value should be greater than the value configured for the cumulative acknowledgment timer by using the ss7 session cumack_t command.
Examples
The following example sets up two sessions and specifies 550 milliseconds as the time to wait for an acknowledgment for each session:

12.1(2)XH
This command was implemented for Cisco MC3810 and for Cisco 2600 and 3600 series routers.
12.1(3)T
This command was first supported on the T Train.
Usage Guidelines
This optional command is configured on FXS voice ports that are used to originate on-net calls. The information entered is displayed by the telephone attached to the FXS port at the far end of the on-net call. It can also be configured on the FXO port of a router on which Caller ID information is expected to be received from the CO, to suit situations where a call is placed from the CO, then goes through the FXO interface, and continues to a far-end FXS port through an on-net call. In this case, if no Caller ID information is received from the CO telephone line, the far-end call recipient receives the information configured on the FXO port.
Note
Do not use this command when the Caller-ID standard is dual-tone multifrequency (DTMF). DTMF Caller ID can carry only the calling number.
If the station-id or caller-id alerting command is configured on the voice port, these automatically enable Caller-ID, and the caller-id enable command is not necessary.
This command applies to the Cisco MC3810 and to Cisco 2600 and 3600 series routers.

Command History
12.1(3)T
This command was introduced on the Cisco 2600, 3600, and MC3810 series.
Usage Guidelines
The supervisory disconnect anytone voice-port configuration command can be used to provide the disconnect function if the PBX or PSTN does not provide a supervisory tone. This function is enabled only during call setup (before the call is answered); examples of tones that trigger a disconnect include busy tone, fast busy tone, and dial tone. You must enable echo cancellation; otherwise, the router's own ringback tone can trigger a disconnect.
This command replaces the no supervisory disconnect signal command. If you enter the no supervisory disconnect signal command, the supervisory disconnect any-tone feature will be enabled, and "supervisory disconnect" anytone will be displayed when show commands are entered.
Examples
The following example configures voice ports 1/4 and 1/5 to go on-hook if any tone from the PBX or PSTN is detected before the call is answered:

12.1(3)T
This command was introduced on the Cisco 2600, 3600, and MC3810 series.
Usage Guidelines
You can apply an FXO supervisory disconnect tone voice class to multiple voice ports. You can assign only one FXO supervisory disconnect tone voice class to a voice port. If a second voice class is assigned to a voice port, the second voice class replaces the one previously assigned. You cannot assign separate FXO supervisory disconnect tone commands directly to the voice port.
This feature is applicable to analog FXO voice ports with loop-start signaling.
Examples
The following example assigns voice class 70 to FXO voice port 1/5 of a Cisco MC3810 series concentrator and specifies tone detection during the entire call duration:

no tech-prefix number
Syntax Description
Defaults
No technology prefix is defined.
Command Modes
Dial-peer configuration
Command History
Usage Guidelines
Technology prefixes are used to distinguish between gateways that have specific capabilities within a given zone. In the exchange between the gateway and the gatekeeper, the technology prefix is used to select a gateway after the zone has been selected. Use the tech-prefix command to define technology prefixes.
Technology prefixes can be used as a discriminator so that the gateway can tell the gatekeeper that a certain technology is associated with a particular call (for example, 15# could mean a fax transmission), or a technology prefix can be used like an area code for more generic routing. No standard defines what the numbers in a technology prefix mean; by convention, technology prefixes are designated by a pound (#) symbol as the last character.
In most cases, there is a dynamic protocol exchange between the gateway and the gatekeeper that enables the gateway to inform the gatekeeper about technology prefixes and where to forward calls. If, for some reason, that dynamic registry feature is not in effect, you can statically configure the gatekeeper to query the gateway for this information by configuring the gw-type-prefix command on the gatekeeper. Use the show gatekeeper gw-type-prefix command to display how the gatekeeper has mapped the technology prefixes to local gateways.
Note
Examples
The following example defines a technology prefix of 14# for the specified dial peer. In this example, the technology prefix means that the H.323 gateway will ask the RAS gatekeeper to direct calls using the technology prefix of 14#.

threshold noise
To configure a noise threshold for incoming calls, use the threshold noise command in voice-port configuration mode. To restore the default, use the no form of this command.
threshold noise {value}
no threshold noise {value}
Syntax Description
value
Number that establishes a noise threshold. Valid values are from -30 to -90 decibels (dBs). The default value is -62 dB.
Defaults
-62dB
Command Modes
Voice-port configuration
Command History
Usage Guidelines
Cisco voice activity detection (VAD) has two layers: application programming interface (API) layer and processing layer. There are 3 states that the processing layer classifies incoming signals: speech, unknown, and silence. The state of the incoming signals is determined by the noise threshold.
In earlier Cisco IOS Releases, the noise threshold is fixed between -62dB and -78 dB. If the voice level is below the noise threshold, then the signal is classified as silence. If the incoming signal cannot be classified, the variable thresholds that are computed with the statistics of speech and noise that VAD gathers is used to make a determination. If the signal still cannot be classified, then it is marked as unknown. The final decision is made by the API. For applications such as hoot-n-holler, you could have the noise create unwanted spurious packets (for example, a voice stream) taking up bandwidth.
With Cisco IOS Release 12.2(16), the noise threshold is configurable using the threshold noise command.
Examples
The following sample configuration shows a noise threshold level of -50 dB configured on a Cisco 3600:
voice-port 1/0/0threshold noise -50timeouts call-disconnect
To configure the call disconnect timeout value for a specified voice port, use the timeouts call-disconnect command in voice-port configuration mode. To restore the default value, use the no form of this command.

This command was integrated into Cisco IOS Release 12.0(4)T.
Usage Guidelines
This command applies to Cisco 3600 series routers. To disable the timeouts call-disconnect timer, set the seconds value to 0. Use the timeouts call-disconnect command to specify the number of seconds for which the originating end system waits after receiving disconnect before notifying the user to hang up by playing a fast busy tone. During this duration, the user just hears silence. If the command is disabled by setting the value to 0, the user hears silence indefinitely.
Examples
The following example sets a call-disconnect timeout value of 10 seconds on a Cisco 3600 series router voice port:
voice-port 1/0/0timeouts call-disconnect 10Related Commands
